My reading of schema datatypes is that with a union type:
o a lexical form can be ambiguous - i.e. might map to different values
depending on which component type is used to do the mapping
o the component types of a union are ordered by the order they are
declared when defining the union
o by default the ambiguity is resolved by applying the first type whose
lex space includes the literal
o the default can be overridden by using an xsi:type attribute
In RDF we always use the default disambiguation rule. If you want to
override, use a more specific datatype in the rdf:datatype attribute.
I guess I'm missing something.
